ICETOOL SORT Operator

SORT operator sorts the records in the input file and copies the records into the output files. It allows up to 10 input files.

Syntax -

SORT Operator

Required Operands

  • FROM - specifies ddname of the input file. It is mandatory when FROM operand is coded.
  • JKFROM - used to JOIN KEYS for matching records. It is mandatory when USING(xxxx) is coded. In xxxxCNTL, a JOINKEYS statement should provide F1=ddname1 for the F1 file, F2=ddname2 for the F2 file, JOIN and REFORMAT statements according to the requirement.
  • USING - specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement. XXXX name is the user-defined name. Either TO, USING, or both operands can code at the same time.

Optional Operands

  • TO - specifies 1 to 10 ddnames of output files. TO and USING operands can code at the same time.
  • VSAMTYPE - specifies the record format for a VSAM input file. It should be either F (fixed-length) or V (variable-length) record processing.

Example -

Scenario - Sort the employee records based on employee name (15 character length from 6th position).
